Thanks for your assistance. I have now completed the Haldex oil changed and would class it as a simple-ish task however it took me a while to build the confidence to do it
. Just needed to check I had the tools required and could open the fill cap. Start to finish took me around 2 hrs with plenty of time cleaning and checking but could do it much quicker now. The filter was not pleasant to see and some of the nets where completely blocked. Well worth doing.
